Abstract
A display apparatus, a pixel circuit, and a method for driving a pixel circuit are provided. The pixel circuit comprises: a first storage sub-circuit, connected between a first node and a second node; a driving sub-circuit, used to control connection or disconnection between the third node and the fourth node under control of the first node; wherein the third node is connected to a first power supply terminal; a light-emitting control sub-circuit, used to control connection or disconnection between the fourth node and the first electrode of the sub-pixel; a second storage sub-circuit, used to store a potential of the first node; a data writing sub-circuit, used to input a voltage to the second node; and a compensation sub-circuit, used to control connection or disconnection between the first node and the third node under control of the first scanning signal terminal, or, used to control connection or disconnection between the first node and the fourth node under the control of the first scanning signal terminal. The present disclosure can improve the display effect.
